What Does Read-Write Memory (RWM) Mean?
Read-write memory (RWM) is computer memory that can be read from and written to. This type of memory can be contrasted with read-only memory, which cannot be modified after it is written. Both of these contrast with another, more obscure, type of memory called write-only memory, which is very narrowly applied to hardware setups.
Techopedia Explains Read-Write Memory (RWM)
In general, the use of read-write memory represents the need for users to continually update the data that is held on hardware storage devices. Any other kind of memory other than read-write memory wouldn’t make sense for a large number of technologies because the data that will be stored on them is not supposed to be static, but depends on immediate use and user preference.
